What does this plugin do exactly?

It adds meta data to your wordpress blog so it can better interact with facebook and other services that use the open graph protocol.

Did you make this plugin all by yourself?

The original code for this plugin was written by Joe Crawford, but I have extensively modified it and hopfully improved upon what he originally wrote!

Only the default image is being used, whats wrong?

You need to add an image as a featured image for this plugin to work correctly.

It doesn't seem to be working correctly, whats wrong?

You may not have entered your Facebook ID and your Facebook Application ID, if you have, double check it, and make sure it's correct!

Why have you updated so many times since its been submitted?

I'm new to working with WordPress, so there will be updates to correct errors to make sure it works perfectly for everyone who downloads this!

How do I replace the default image?

Go to "wordpress directory"/wp-content/plugins/wp-ogp and replace default.jpg with another image with the same name! This only works for the default image, you need to add a featured image on the post page for it to work with articles.

How do I register a new application with Facebook?

Go to http://www.facebook.com/developers and allow the developer application access to your account. As of writing this, there is an issue with this and you will be presented with an 404 error after it redirects you back to facebook. - Screenshot 3
